The first thing after bought the car
Give new car film
However, there are many types of automotive membranes on the market.
If you bought it wrong
Not only can’t protect the car
It is also possible to cause a vague of sight.

Unqualified project analysis
The unqualified items involved in this spot check are: visible light transmission ratios, ultraviolet transmissions, visible light reflection ratios, and temperature resistance items.
The visible light transmissive ratio requires that the visible optical transmissive ratio is ≥78%, and the visible light transmissive transmissive is 15% to 50%. There are 2 batches of the front-end sun visible light-transmissive sun visible light-transmit ratio items in this spot check, and the minimum value is only 64%; there are 5 batch of lateral sun visor product visible light transmission ratio items do not meet the standard requirements, minimum Only 6%. Visible light transmissions will not be qualified to seriously affect the sight of the driver, endanger the personal safety of the driving passengers.
Ultraviolet transmission ratio requires the ultraviolet transmissive ratio of the car window glass sun visor in the project standard to be less than or equal to 1%. This test has 4 batches of products that ultraviolet transmission ratio projects do not meet the relevant standard requirements, of which 1 batch reaches 27%. Ultraviolet transmission ratio does not meet the requirements requirements cannot effectively resist harmful ultraviolet irradiation, which is easy to lead to redness of the driver’s skin, producing blisters, peeling.
The visible light reflection is required to be less than or equal to 20% in the visible light reflection ratio of the visible light reflection. This test has 1 batches of sample visible light reflection ratio does not meet the requirements. The visible light reflection of the car window glass visible is too high to interfere with the driving of the driving passengers to form a safety hazard. At the same time, the vehicle traveling on the front and rear, has a strong light reflection, bringing the corresponding driver’s eyes discomfort, bringing certain safety Hidden dangers.
After the temperature test is required, the car window glass sun visor should not produce softening, glue, wrinkles, cracks, discoloration, dissolution, or other significant defects. There were 1 batches of temperature resistance in this spot check, and there were multiple bubbles after the temperature test, which was prone to the driving of the driving personnel.
Unqualified reason
The reason for causing the visible light transmissive ratio is primarily due to the production of product quality control, improper process adjustment, and use inferior base membranes. In addition, in order to achieve other performance requirements such as anti-UV, heat insulation, the manufacturer is added to the material, which may also reduce the visible light transmission ratio of the product.
UV transmission ratio is unqualified is that the manufacturer is not strict, and the ultraviolet shielded material or ultraviolet absorber added during production process does not satisfy the requirements, ultimately leading to the ultraviolet transmissive ratio to the standard requirements.
The visible light reflection is unqualified. It may be that the production enterprise adds too much reflective material to achieve more reflection in the production process, which ultimately leads to a visible light reflection and far exceeding the standard requirements.
The temperature resistance is unqualified is mainly due to the production process of the enterprise, and the production technology is lagging behind.
Consumption Tips
Try to purchase a car window glass sun visor with a regular automotive product store, car car wash beauty store and automobile wholesale market.
Shopping car window glass sunshade. Regardless of the car window glass sun visor, the high-quality car window glass sunshade is relatively clear, and there is a feeling of foggy.
Select high quality car window glass sun visor. After torn the plastic liner of the car window glass visor, when recombining, the inferior film will bubble, and the high-quality film is complete, and the adhesive of the high-quality film will be firmly pasted on the sun visor without residual. On the car glass or plastic lining; the high quality car window glass sun visor has thick and smooth feelings, and the inferior sun visor is thin, and it is easy to wrinkle.
When purchasing a car window glass visor, try to clear the product specification model, batch number, etc., and ask for samples for automotive film, and keep samples such as samples, and safely defend in the shelf life.
